ABSTRACT
The technology of vacuum brazing components of aluminium and its alloys requires a high vacuum (residual pressure p0 = 10"2–103 Pa) and the introduction of an evaporation getter – magnesium. This requires expensive special equipment with a relatively low productivity even in the presence of multi-chamber continuous furnaces. In addition, it is necessary to clean the chamber and other sections of the vacuum system often to remove the condensate of magnesium and its oxides, with partial dismantling of the furnace. In this article, the authors present the results of investigations into the evaporation of magnesium, the interaction of its vapors with AMts alloy and the special features of formation of brazed joints under low vacuum conditions.
